Cookies

No advertising cookies, no audience measurement, no third-party trackers. The showcase pages set no cookie. The customer area sets two strictly necessary cookies, which need no consent: “lum” (login session and security token, 30 days at most) and “lum_auth” (a simple “signed in” flag with no personal data, 30 days). Signing out removes them. The installable web app keeps your data in your browser storage, on your device only.
